We're being asked to calculate the number of atoms contained in 51.6 mL mercury (Hg). The density of Hg is 13.5 g/mL.
We can calculate the number of atoms present in 51.6 mL of mercury (Hg) using the following sequence of calculations:
Volume Hg (Density Hg) → Mass Hg (Molar Mass Hg) → Moles Hg (Avogadro's number) → # of Hg atoms
We're given the following values:
Volume = 51.6 mL
Density = 13.5 g/mL
Constants we need:
How many atoms are contained in 51.6 mL mercury (Hg)? The density of Hg is 13.5 g/mL.
a. 1.11 x 10-2
c. 6.68 x 1021
d. 2.09 x 1024
e. 8.41 x 1028
